Subject: [PATCH v4 8/8] usb: misc: onboard_hub: add support for XMOS XVF3500
Date: Tue, 20 Feb 2024 15:05:52 +0100 [thread overview]
Message-ID: <20240220-onboard_xvf3500-v4-8-dc1617cc5dd4@wolfvision.net> (raw)
In-Reply-To: <20240220-onboard_xvf3500-v4-0-dc1617cc5dd4@wolfvision.net>
The XMOS XVF3500 VocalFusion Voice Processor[1] is a low-latency, 32-bit
multicore controller for voice processing.
This device requires a specific power sequence, which consists of
enabling the regulators that control the 3V3 and 1V0 device supplies,
and a reset de-assertion after a delay of at least 100ns. Such power
sequence is already supported by the onboard_hub driver, and it can be
reused for non-hub USB devices as well.
Once in normal operation, the XVF3500 registers itself as a USB device,
and it does not require any device-specific operations in the driver.
